Trump received sweeping condemnation after saying he saw Arab and Muslim Americans publicly rejoicing the unprecedented terror attacks.

Republican U.S. presidential frontrunner Donald Trump on Sunday refused to take back claims that he saw Muslims cheering in New Jersey after the September 11, 2001 attacks, despite a lack of proof.

“It was 14 years ago but I saw it on television, I saw clips and so did many other people,” Trump told the U.S.-based NBC’s “Meet the Press” talk show.

Within days of 9/11, police, fact-checkers and U.S. media debunked the rumors that people were cheering from rooftops of Jersey City, across the river from Manhattan.

Still, Trump stood by his comments: “I saw it. So many people saw it… And so why would I take it back? I’m not going to take it back.”

Trump cited an article written by The Washington Post at the time saying authorities detained “a number” of people supposedly seen cheering in New Jersey.

But there was no indication in the article of thousands or even hundreds of Muslims cheering.

Nonetheless, the real-estate tycoon told “Meet the Press” that “we’re looking for other articles and we’re looking for other clips and I wouldn’t be surprised if we found them,” he said.

“But for some reason they’re not that easy to come by.”
